Avocado is a wonderful addition to cold process soap, featuring:
- skin-loving nutrients,
- essential fatty acids,
- and lots of label appeal.
Here’s how to add avocado to your soap recipes!

7 quick tips when making avocado soap:
- Try replacing up to 1/3 of the water amount in your recipe with mashed avocado. If your recipe calls for 9 ounces of water, try 6 ounces of water plus 3 ounces of mashed avocado.
- Blend the avocado into the warmed oils, before adding the lye solution.
- Thoroughly blend the avocado with an immersion blender, since large chunks can spoil in soap.
- Avocado will not stay green in soap, so try adding 1 to 2 tsp PPO* French green clay or chlorella powder for a natural green color. (PPO = per pound of oil in the recipe. 1 pound = 16 ounces = 454 grams.)
- It’s often best to avoid gel phase, since avocado tends to darken and brown when it gets heated up.
- Pour soap batter into individual molds and place them in the fridge for about 24 hours before returning to room temperature.
- Soaps made with avocado have a similar shelf life as regular soap; the high pH of soap is protective against it spoiling.
Here’s a bonus tip and helpful idea kindly shared by reader & soapmaker Penny:
“I mash an avocado with a bit of oil and grapefruit seed extract and freeze it. I make a hot process batch all the way thru the cook, stir in the avocado into half the soap and make a swirled batch.”
Below is a recipe from my Simple & Natural Soapmaking print book, but feel free to use the tips above to add avocado to your own favorite soap recipes.

Directions to Make
If you’ve never made soap before, stop and research the process before proceeding.
Wearing protective gloves and eyewear, carefully stir the lye into the distilled water. Stir in the French green clay and set aside to cool for about 30 to 40 minutes, or until it’s around 100 to 110 degrees F (38 to 43 C).
Melt the solid fats (butter and coconut oil) and mix with the other oils. Check the temperature and cool or warm as needed, so that the oils are around 100 to 110 degrees F. (Lye solution and oils do not have to be the same temperature, ball park temperatures are fine.)
Blend the avocado into the oils with an immersion blender until there are no large pieces of avocado visible, since they can spoil in the soap.
Pour the lye solution into the oils. Using a combination of hand stirring and stick blending, mix until the soap reaches light trace.
To preserve the color of the soap, put the filled molds in the refrigerator for about 24 hours. Individual molds work best to prevent partial gel.
After removing from the fridge, let the mold sit an additional day or two before removing the soaps.
Cure in the open air for at least 4 to 6 weeks before using.
